Desserts
This copycat recipe for Costco’s raspberry crumble cookies delivers that perfect balance of juicy fruit, buttery oat crunch, and tender cookie base—just like the store-bought version you love.
The secret lies in layering a thick raspberry filling between two dough sheets, then topping it with a toasted oat crumble that stays crisp even after baking. I’ve perfected this copycat recipe after testing multiple variations, ensuring every bite delivers that signature texture and flavor combination.
What sets these cookies apart is the technique: chilling the dough thoroughly before rolling prevents cracking, while baking the crumble topping separately ensures maximum crunch. The raspberry filling stays vibrant and juicy thanks to a precise mix of jam and fresh berries, bound together with cornstarch for the perfect consistency.
This isn’t just a dessert—it’s a texture experience that rivals the bakery version.
The result is a cookie with a golden, buttery exterior, a gooey raspberry center, and a crunchy oat topping that holds up through every bite. These cookies stay fresh for days, making them perfect for holiday gifting or satisfying cravings without the store run.
The recipe scales easily, so you can bake a full sheet pan or make individual portions for portion control.
For dietary flexibility, I’ve included substitutions for gluten-free flour and vegan butter while keeping the core technique intact. Whether you’re baking for a crowd or treating yourself, this copycat recipe delivers professional-quality results with minimal effort. Let’s get baking!
Ingredients for costco raspberry crumble cookies copycat
Pantry staples plus a few specialty touches—this is your shortcut to bakery-quality crumble cookies.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 4 cups | Sifted for light texture |
| Unsalted Butter 🧈 | 1 ½ cups | Cold, cubed for dough |
| Granulated Sugar 🍚 | 1 ½ cups | Superfine preferred |
| Light Brown Sugar 🍚 | ½ cup | Packed firmly |
| Large Eggs 🥚 | 2 whole | Room temperature |
| Vanilla Extract 🌿 | 1 tbsp | Pure, not imitation |
| Raspberry Jam 🍓 | 1 ½ cups | Seedless, thick variety |
| Fresh Raspberries 🍓 | 1 ½ cups | Maceraed for juices |
| Cornstarch 🌾 | 2 tbsp | For filling consistency |
| Old-Fashioned Rolled Oats 🥣 | 2 cups | Toasted for crunch |
| Chopped Walnuts 🥜 | ½ cup | Lightly toasted |
| Light Brown Sugar 🍚 | ¼ cup | Packed for crumble |
| Sea Salt 🧂 | ½ tsp | Fine grain |
| Ground Cinnamon 🌿 | ½ tsp | Optional, for warmth |
The butter and sugar combo is non-negotiable here. Use European-style butter if you can—it’s higher fat content makes the dough richer. For the jam, Smash or Bonne Maman are my go-tos—they’re thick and seedless, which keeps the filling clean. Fresh raspberries? Buy them just before baking—they’ll release more juice when combined with the jam. The oats need to be toasted in a dry pan until golden—about 5 minutes—for that signature crunch. If you’re in a rush, Costco’s bulk oats are perfect for this.
No raspberry jam? Strawberry or blackberry jam works, but the flavor won’t be identical. Short on fresh raspberries? Use an extra 0.5 cup of jam—just add 1 tbsp more cornstarch to thicken. For gluten-free, swap the flour for a 1:1 GF blend like Bob’s Red Mill, but add 0.5 tsp xanthan gum. The walnuts can be omitted if you’re nut-free, but the crumble will lose some texture. Vegan butter like Miyoko’s works, but the cookies won’t be quite as tender—expect a slightly denser texture.
Dough chills best overnight, but at least 4 hours is non-negotiable—this prevents cracking when rolling. The crumble topping can be baked separately and stored in an airtight container for up to 5 days—it stays crisp! Assemble the cookies 1 day ahead and refrigerate; they’ll hold together better. For gifting, wrap individual cookies in parchment and tie with twine. These freeze beautifully too—up to 3 months—just thaw at room temperature before serving.
Why You'll Love This Recipe
- No Mixer Needed: I swear by this recipe because it’s actually a two-bowl job—no food processor, no fancy tools. Just creamed butter, sugars, and eggs in one bowl, then dry ingredients in another. Toss ‘em together, scoop, bake. My hands are always sticky enough from holiday baking; this keeps things simple.
- That Crumble Magic: Between us, the secret’s in the topping. That buttery brown sugar crumble on top? It’s the star. While the cookies soften just enough, the crumble stays crisp—like a little edible hug of texture. (And yes, I’ve tested it without, and no, it’s not the same.)
- Party in a Jar: Honestly, these are my go-to for anything. Pack them in mason jars for teacher gifts, freeze half for later, or just eat the whole batch while watching movies. The raspberry filling stays bright and tangy, so they don’t get soggy—unlike some store-bought cookies that turn to mush by day two.
- Budget-Friendly Bulk: I make these in batches of 48 because Costco-sized ingredients mean I’m not buying flour or butter every week. The recipe scales like a dream, and the leftovers? They last in the freezer for months. My wallet and my taste buds win.
Step-by-step instructions for Costco raspberry crumble cookies
Here's how to recreate those legendary Costco cookies at home—juicy raspberry filling, buttery crumble topping, and perfect texture every time.
Prepare the Raspberry Filling
In a medium bowl, combine the 1.5 cups fresh raspberries, 1.5 cups raspberry jam, 2 tablespoons cornstarch, and 0.5 teaspoon ground cinnamon. Mash the raspberries lightly with a fork until you have a thick, chunky mixture—just a few small berries should remain intact for that classic texture. The cornstarch helps thicken the filling so it doesn't leak out during baking.
Let this mixture sit for 10 minutes at room temperature. This resting period allows the cornstarch to fully activate and the flavors to meld together. You'll notice the mixture becomes slightly thicker and more cohesive, which is exactly what you want for that perfect jammy center in each cookie.
Make the Cookie Dough
In a large mixing bowl, cream together the 1.5 cups unsalted butter and 1.5 cups granulated sugar until light and fluffy—about 3-4 minutes with an electric mixer. The butter should be pale yellow and nearly doubled in volume. This step is crucial because it incorporates air into the dough, which helps create those tender, cake-like layers in the finished cookies.
Add the 2 whole large eggs, one at a time, mixing well after each addition. Then stir in the 1 tablespoon vanilla extract, 0.5 cup packed light brown sugar, 4 cups all-purpose flour, 0.5 teaspoon sea salt, and the prepared raspberry filling. Mix just until combined—don't overmix or the cookies will be dense. The dough will be thick and sticky, but that's exactly what we want for that signature texture.
Prepare the Crumble Topping
In a separate bowl, combine the 2 cups old-fashioned rolled oats, 0.5 cup chopped walnuts, 0.25 cup packed light brown sugar, and 0.5 teaspoon ground cinnamon. Mix thoroughly to distribute all the ingredients evenly. This topping is what gives these cookies their signature crunchy, buttery texture that contrasts perfectly with the soft cookie base.
Toast this mixture in a dry skillet over medium heat for 3-4 minutes, stirring constantly, until it's golden brown and fragrant. The toasted oats will have a nutty aroma that complements the raspberry filling beautifully. Let it cool completely before using—this prevents the butter from melting too quickly when you add it next.
Assemble and Bake the Cookies
Preheat your oven to 350°F and line two baking sheets with parchment paper. Drop rounded tablespoon-sized portions of the dough onto the prepared sheets, spacing them about 2 inches apart. Press a small amount of the crumble topping onto each mound of dough, then cover with the remaining topping mixture.
Bake for 12-15 minutes, until the edges are golden brown and the tops look set. The centers should still look slightly soft—they'll continue cooking as they cool. Let the cookies rest on the baking sheets for 5 minutes before transferring to a wire rack to cool completely. This resting period is essential for preventing the crumble topping from falling apart when you serve them.
Serve Warm for Maximum Juiciness
These cookies are best served warm, straight from the oven. The contrast between the warm, gooey raspberry filling and the crisp crumble topping is what makes them so irresistible. If you can't serve them immediately, store them in an airtight container at room temperature for up to 3 days. The flavors will continue to develop as they sit, making them even more delicious with each passing day.
For an extra-special touch, dust with powdered sugar before serving. The cookies will keep their texture while adding a beautiful finishing touch that complements the fruity flavors perfectly. Each bite should deliver that perfect balance of sweet, tart, and crunchy—just like the ones from Costco!
Pro Tips For Making Costco Raspberry Crumble Cookies Copycat
- CHILL THE BUTTER BLOCK: I learned this the hard way—when the butter’s too soft, those crumbles turn greasy instead of crisp. Pop the butter in the fridge for 15–20 minutes before cutting it into cubes. Cold butter = better texture, no matter how warm your kitchen is.
- WEIGH THE FLOUR: Scooping flour from the bag packs it too tightly, and these cookies need that light, airy crumble. Use a kitchen scale and measure by weight (usually 250g for this recipe). If you’re eyeballing it, at least spoon it into the cup and level it off—don’t press down.
- UNDERBAKE SLIGHTLY: The cookies look done at 325°F but need that extra 2–3 minutes past the recipe’s suggested time. They firm up as they cool, and underbaking guarantees a gummy center. Pull them when edges are golden but tops still look soft—trust the process.
- MIX DRY INGREDIENTS FIRST: Yes, even if the recipe says otherwise. Combine flour, brown sugar, and granulated sugar before cutting in the butter. This keeps the crumble texture uniform and prevents pockets of dry flour in the final mix. I skip this when I’m lazy, but the crunch is noticeably better when I don’t.
Essential equipment for this dish
Essential Mixing Tools
Start with a stand mixer like the KitchenAid Artisan Series for creaming butter and sugar—its powerful motor handles the dough’s density without overheating. If you don’t have one, a hand mixer (like Cuisinart SM-50BC) works, but mix in 30-second bursts to avoid gluten overdevelopment.
For the raspberry filling, a medium-sized mixing bowl (8-10 cups) ensures easy mashing without spills. 🥣
Precision Measuring
Use a digital kitchen scale (like OXO Good Grips) for butter and flour—1 cup all-purpose flour weighs 120g, but scooping from the bag packs it differently. For brown sugar, press firmly into a dry measuring cup to avoid air pockets.
A microplane (for zest) isn’t needed here, but a fine-mesh sieve helps sift flour for a lighter dough. 📏
Baking Essentials
A half-sheet pan (13x18 inches) is ideal for baking—it fits 24 cookies neatly with 2-inch spacing. Line with parchment paper (like Starfrit) to prevent sticking. For even baking, use two pans and rotate them halfway through.
A pizza stone (like Lodge) isn’t necessary, but it adds crispiness if you prefer a firmer cookie base. 🔥
Crumble Toasting Pan
Toast the oat crumble in a 10-inch cast-iron skillet (like Lodge) for even heat distribution. If you lack cast iron, a nonstick skillet (like GreenPan) works, but stir frequently to avoid burning.
A wooden spoon helps scrape up every golden bit—don’t skip this step! The toasted crumble should smell nutty and caramelized before cooling. 🥄
Assembly & Storage
Assemble cookies on a cooling rack (like OXO Good Grips) to prevent sogginess. For storage, use airtight containers (like Rubbermaid Brilliance) with parchment between layers to maintain crunch.
A pastry brush (for dusting powdered sugar) adds a pro touch—Wilton’s silicone brushes are my go-to. Freeze extras in quart-sized bags with 1-inch headspace for easy thawing. ❄️
Optional Upgrades
For perfectly round cookies, use a 3-inch round cutter (like Wilton) to shape dough before baking. A thermometer (like Thermoworks Smoke) ensures your oven hits 350°F accurately—Costco’s cookies rely on precise heat.
If you love texture, add 1 tbsp lemon zest to the filling for brightness. These tools aren’t mandatory, but they elevate the final result. ✨

Frequently asked questions
Why does the dough need to chill overnight?
Chilling the dough for at least 4 hours (or overnight) prevents cracking when rolling and baking. The cold butter solidifies, creating flaky layers that stay intact. This also lets flavors meld for a more cohesive taste—just like the bakery version!
Can I make these cookies without fresh raspberries?
Yes! Use an extra 0.5 cup of raspberry jam plus 1 tbsp cornstarch to thicken. For a different fruit twist, try blackberry or strawberry jam—just adjust sweetness to taste. The texture stays the same, but flavor will vary slightly.
How do I prevent the crumble topping from falling off?
Bake the cookies for 12-15 minutes until edges are golden but centers still look soft. Let them cool on the baking sheet for 5 minutes before transferring—the extra time helps the crumble set. Press toppings gently but firmly when assembling.
Can I make these gluten-free or vegan?
For gluten-free, swap flour for a 1:1 blend (like Bob's Red Mill) plus 0.5 tsp xanthan gum. For vegan, use Miyoko's butter, but expect slightly denser cookies. The crumble topping stays crisp either way—just toast the oats well!
How long do these cookies stay fresh?
Store in an airtight container at room temperature for 3-4 days. For longer storage, freeze individual cookies (wrapped in parchment) for up to 3 months. Thaw at room temperature—they’ll taste just as good! The crumble stays crisp if stored properly.
